Questions

In countdown I don’t understand why we have to set like that. (question)
there are two data to work on, current time and ‘date/time picker’ value time.

text data source for displaying date:
set time - current time; formatted as seconds /60/60/24<-modulo->365-0.5:rounded to 0.

  1. Can you explain the .../60/60/24<->modulo365-0.5;rounded to 0?
  2. what is ;rounded to?

Thanks…
